Page 1 Specifications Mechanical Characteristics Item Test Condition Evaluation Standard Solderability Lead terminals are immersed in rosin for 5 seconds and then immersed in the solder bath at +250±5℃ for 3±1 seconds. 90% min. lead terminals shall be wet with solder. (Except the edge of terminal) Soldering Heat Resistance Lead terminals are immersed in the soldering bath at +250±5℃ for 3±1seconds.The force of 9.8N(1.0Kg) is applied to the part for 10 seconds. No interference in operation. Terminal Mechanical Strength The force of 9.8N is applied to each terminal in axial direction for 10 seconds. No damage and cutting off. Vibration The buzzer shall be measured after a vibration of amplitude of 1.5mm with 10Hz to 55Hz band of vibration frequency is applied to each of 3 perpendicular directions for 2 hours Drop Test The part is dropped from a height of 75cm onto a 40mm thick wooden board 3 times in 3 axes (X,Y,Z). A total of 9 times. The value of oscillation frequency current consumption should be in±10% compared with initial ones. The SPL should be in±10dB compared with initial one.
